Title: SonicWALL Global VPN Client Remote Format String Vulnerability
Severity: HIGH
Description:
SonicWALL Global VPN Client provides virtual private networking for mobile users.
The application is prone to a remote format-string vulnerability because it fails to properly sanitize user-supplied input before passing it as the format specifier to a formatted-printing function.
Attackers can trigger the issue by supplying a specially crafted configuration file that contains format specifiers. Specifically, the 'name' attribute of the 'Connection' tag and the value of the 'Hostname' tag can be used to trigger this issue.
To exploit this issue, an attacker must trick a victim into processing a malicious configuration file with the affected application.
Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the application. Failed attempts may cause denial-of-service conditions.
Versions prior to SonicWALL Global VPN Client 4.0.0.830 are affected.
Affected Products:
- SonicWALL Global VPN Client 4.0.0.782
